Sherrer is an attorney who represents HD8, which covers portions of Mayes, Rogers, and Wagoner counties. He is in his final term as a state representative.

Ellis represents SD5, which covers Choctaw, McCurtain, Pushmataha, and portions of Atoka and LeFlore counties in far southeast Oklahoma. Ellis formerly served in the State House, but ran for SD5 two years ago, prompting a special election this year due to term limits cutting his senate term in half. Ironically, Ellis' district just went Republican.

I know nothing about Shiefelbein other than he is an attorney from Tahlequah.

Whomever the ODP ultimately selects as their replacement candidate will go up against Republican Congressman Markwayn Mullin and Indepedent Jon Douthitt, assuming a special election is called (which according to my reading of the statute is inevitable).
